AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DENVER/BOULDER CO 842 PM MDT MON AUG 25 2014 .UPDATE... ISSUED AT 831 PM MDT MON AUG 25 2014 LINE OF STRONG STORMS CONTINUE TO MARCH EASTWARD ACROSS THE FAR EASTERN PLAINS WITH THE BULK OF ACTIVITY ACROSS EASTERN WASHINGTON AND LINCOLN COUNTIES WITH GUSTY WINDS AND HEAVY RAIN. EXPECT MOST OF THIS ACTIVITY TO CLEAR FROM WEST TO EAST INTO KANSAS BETWEEN 10 PM AND MIDNIGHT. STRONGEST STORMS STILL DEVELOPING ON THE SOUTHERN FLANK THROUGH LINCOLN COUNTY WITH LOCALIZED PULSE SEVERE STORMS THERE. FURTHER WEST...VERY ISOLATED ACTIVITY OVER FRONT RANGE AND MOUNTAINS. WILL ADJUST FORECASTS FOR THESE LATEST TRENDS. MODELS STILL SHOW AN INCREASE IN LOW LEVEL MOISTURE OVERNIGHT LEADING TO STRATUS AND PATCHY FOG. WILL UPDATE GRIDS TO ADD FOG. CURRENT SEVERE THUNDERSTORM WATCH UNTIL 04Z...AND THAT SHOULD BE ABOUT THE RIGHT TIME FOR REDUCED THREAT OF SEVERE STORMS. && .SHORT TERM...(THIS AFTERNOON THROUGH TUESDAY) ISSUED AT 234 PM MDT MON AUG 25 2014 COOL AIRMASS HAS MOVED OVER NORTHEAST COLORADO TODAY. EASTERLY LOW LEVEL FLOW HAS INCREASED DEW POINTS THROUGH THE DAY. AS THE AIRMASS CONTINUES TO SLOWLY WARM...THE CAP SHOULD BE BROKEN. STORMS ARE STARTING TO FORM OVER THE HIGHER TERRAIN AND WILL SPREAD EASTWARD THROUGH THE LATE AFTERNOON AND EVENING. STILL A CHANCE FOR SEVERE WEATHER TODAY. SURFACE BASED CAPES WILL CLIMB TO AROUND 1000 J/KG. THIS COMBINED WITH GOOD SHEAR SHOULD RESULT IN A FEW SEVERE STORMS. BEST CHANCE FOR SEVERE WEATHER WILL BE EAST OF I-25 WHERE THE GREATEST MOISTURE AND INSTABILITY WILL RESIDE. HAIL UP TO GOLF BALL SIZE AND WIND GUSTS TO 60 MPH WILL BE POSSIBLE. BECAUSE OF THE SHEAR AND SOMEWHAT LOW LCL...CAN'T RULE OUT A BRIEF TORNADO. SHOWERS AND STORMS WILL PROGRESS EASTWARD THIS EVENING AND IS EXPECTED TO END AROUND OR JUST AFTER MIDNIGHT. DUE THE MOIST SOUTHWEST FLOW ALOFT WILL KEEP LOW POPS IN THE FORECAST FOR LATE TONIGHT AND EARLY TUESDAY. LOW CLOUDS ARE EXPECTED TUESDAY MORNING AND PERHAPS FOG BECAUSE OF THE MOIST LOW LEVELS. SOUTHWEST FLOW ALOFT WILL PREVAIL OVER COLORADO TUESDAY AROUND A CLOSED LOW OVER THE GREAT BASIN. APPEARS THERE WILL BE A WAVE THAT WILL AFFECT THE AREA LATE TUESDAY AFTERNOON AND INTO TUESDAY NIGHT. MOISTURE WILL CONTINUE TO INCREASE WITH PRECIPITABLE WATER VALUES CLIMBING TO AN INCH TO 1.25 ALONG THE FRONT RANGE AND ACROSS THE EASTERN PLAINS. CAPES MAY CLIMB UP TO 2000 J/KG IF TEMPERATURES ARE ABLE TO REACH THE MID TO UPPER 70S. SO THERE WILL BE A CHANCE FOR SEVERE THUNDERSTORMS AGAIN TUESDAY AFTERNOON. BECAUSE OF THE MOIST AIRMASS THERE WILL ALSO BE A SLIGHT CHANCE FOR FLASH FLOODING. STORMS WILL BE MOVING AT A GOOD CLIP...SO THE THREAT WILL BE ON THE LOW SIDE. .LONG TERM...(TUESDAY NIGHT THROUGH SUNDAY) ISSUED AT 234 PM MDT MON AUG 25 2014 FOR WEDNESDAY AND WEDNESDAY EVENING THE MODELS HAVE BECOME IN BETTER AGREEMENT WITH THE PLACEMENT OF THE LOW THAT REACHES CENTRAL UTAH BY 12Z ON WEDNESDAY.

ALONG WITH THE MOISTURE THERE IS DECENT QG ASCENT AND INSTABILITY ON BOTH WEDNESDAY EVENING AND THURSDAY WHEN THE TROUGH MOVES OVER THE CWA. INCREASED POPS ON WEDNESDAY OVER MOUNTAINS AND OVER THE FAR NORTHEAST CORNER. OVER THE PLAINS AND FRONT RANGE ENOUGH WARMING OCCURS ALOFT THAT CONDITIONS WILL INCLUDE MORE RAIN SHOWERS WITH JUST A SLIGHT CHANCE OF THUNDERSTORMS EARLY WEDNESDAY. WILL KEEP TEMPERATURES BELOW SEASONAL NORMALS THROUGH THURSDAY WITH A MIXTURE OF RAIN AND SNOW SHOWERS OVERNIGHT WEDNESDAY INTO THURSDAY FOR AREAS ABOVE TIMBERLINE. PW VALUES ARE STILL HIGH WEDNESDAY THROUGH THURSDAY MORNING AT 0.80-1.00. THERE IS LIGHT STORM MOTION BETWEEN 7 AND 10 KTS SO A POSSIBLE PROLONGED HEAVY RAIN EVENT EXISTS FOR WEDNESDAY EVENING. SYSTEM WILL MOVE OUT OF THE CWA BY FRIDAY AFTERNOON WARMING TEMPERATURES.

SHORT RANGE MODELS SHOW A DENVER CYCLONE TRYING TO DEVELOP LATER TNT WHICH WOULD ADVECT THE LOW CLOUDS/FOG INTO DEN/BJC AFTER 09Z TNT. THERE STILL COULD BE ISOLATED THUNDERSTORMS OVERNIGHT BUT OVERALL CONFIDENCE IS LOW AND NOT ENOUGH COVERAGE TO ADD TO TERMINAL FORECAST. && .BOU WATCHES/WARNINGS/ADVISORIES...
